Abstract:

This study evaluates the biofidelity of Global Human Body Modeling Consortium models representing obese people by comparing their kinematics with obese postmortem human surrogates in frontal sled tests. It was necessary to develop a finite element model to define accurate boundary conditions. Experimental tests with a robotic arm as well as an Instron machine were performed on the seat cushion and seat back foam to characterize the mechanical properties of the buck components. Then, the seat, seat back, frame, and seat reinforcement structure were 3D-scanned, cleaned, and meshed. Finally, the mechanical properties of the buck components were tuned based on the experimental tests. To investigate whether the model is capable of submarining, additional simulations (each with a modification to the model) were performed. The results showed that adding mass to the abdomen or removing the abdominal organs did not change the model’s behavior significantly.
